ABSTRACT:
An air-conditioning method and system controls the temperature of air outputted from an air conditioner outlet duct into the passenger compartment of a vehicle at a constant level, with a small time constant of recovery, by adjusting the air mix door opening percentage. The air-conditioning method comprises the steps of calculating a target outlet duct air temperature on the basis of a preset passenger compartment air temperature, a detected outside-air temperature, and a detected passenger compartment air temperature in accordance with a heat equilibrium equation and calculating an air mix door opening percentage on the basis of the calculated target outlet duct air temperature in accordance with a linear interpolation between two endpoints of a selected one of three characteristics representative of relationships between outlet duct air temperature and air mix door opening percentage respectively stored for outside-air introduction mode, inside-air recirculation mode, and cooler compressor operation mode.
